“…indicate that new bone also showed resorption after the orthodontic treatment and before implantation and advised to postpone the orthodontic treatment until the patient is old enough for implantation. [16] However, other authors claimed that the new bone is stable over long term[613] and age of the patient is not a crucial factor in the decision of treatment time. In the present case, the lateral tooth was moved to midline to form new bone in extraction space.…”

Bone defects at the anterior regions of the jaws often cause esthetic problems such as gingival disharmonies and longer crowns than neighboring teeth. Variety of procedures can be used in this region for achieving sufficient bone volume with or without different bone graft materials. All of these procedures has their own advantages and disadventages. New bone formation was defined with orthodontic tooth movement in different regions. In this case we present the use of orthodontic tooth movement, for achieving sufficient bone volume, in anterior maxillary region, for esthetic and functional results.

“…Two types of treatment are described for congenital agenesis of the LI: space closure with mesial repositioning of the canine, followed by tooth recontouring; or space opening followed by the placement of a prosthesis, transplant, or dental implant 27. The knowledge regarding craniofacial growth and detailed orthodontic treatment is fundamental as it assists correct teeth positioning in both types of treatment and helps to improve the volume of the alveolar ridge for the implant placement 28,29. Several studies have assessed these two treatment options,30–32 and others revealed the opinion of dentists and laypersons concerning smile attractiveness 12,23.…”

BackgroundThe purpose of this study was to associate smile esthetic judgment with dentofacial attributes of patients with unilateral and bilateral agenesis of maxillary lateral incisors treated with recontouring of canines or implants and patients with no agenesis (control).Material and methodsForty-six participants were divided into two groups: those treated with recontouring (N = 26) and those treated with implants (N = 20). The participants in the control group (N = 22) were selected among dentistry students at the State University of Maringá, Brazil. Photographs of posed smiles (17 cm × 10 cm) were evaluated with a 100-mm Visual Analog Scale. Smile attractiveness was judged by two groups: laypersons and dentists (N = 20 in each group). Judgment was classified into Unpleasant and Pleasant. Measurements of 11 smile attributes were done with ImageTool Version 3.0. These measurements were correlated with the type of judgment using the Pearson correlation coefficient.ResultsThe two groups of evaluators showed no rating difference (analysis of variance, P = 0.64), thus they were placed into a single group. No significant correlation was found between esthetic judgment and six smile attributes (incisor exposure, interlabial gap, width 3 to 3, smile index, right buccal corridor, and buccal corridor ratio). The control group showed more correlations with the unpleasant judgment type than the other groups.ConclusionSome correlations between smile attributes and esthetic judgment were found, but other features of smiles not evaluated in this study may interfere in smile attractiveness.
